‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects

The decline of insect populations poses a significant threat to global biodiversity and ecosystems. Climate change remains the primary driver, with insects struggling to adapt due to disrupted life cycles and reduced access to water. Water scarcity further exacerbates these challenges, as surface water is vital for their survival. Seasonal timing plays a critical role in insect reproduction and migration, but climate change disrupts these rhythms, leaving many insects in dire straits. The loss of insects has far-reaching ripple effects on dependent species, highlighting the need for comprehensive ecological management and sustainable practices to ensure recovery.
